Updated again 10/22 (The Hangul--Korean alphabet--address was on there correctly, but the romanized one had 25 instead of 203. I have no idea why):
충청남도 공주시 203번지
Gongju Gyodong Elementary School
203 Gyodong Gong-ju Chung-cheong namdo
Republic of Korea 314-090
Write to me! I promise to write back--on
cunnin' Korean stationery, no less.
